Grow Light Bulb Wattage Calculator
the ideal wattage of your grow light is critical for a
successful indoor garden. The wattage determines the strength of light
supporting your plants.
It is recommend that you provide your plants 50 watts of grow light per square foot
in the growing area. Insufficient light will result in
unhealthy leggy plants that produce low yields.
When entering your measurements, either round up to the
next foot or use decimals for more accuracy. (sorry-fractions won't work)
